姜荷花花茎氮磷钾含量与开花品质的相关性研究

以姜荷花‘清迈粉’品种为材料，于7月中旬、8月下旬和10月上旬分别取样测定了株高、花茎长、花序长及花序展开直径，同时对其根系、花茎、叶、原种球及新生仔球的全氮（N）、全磷（P）和全钾（K）等含量进行了测定，并进行了相关性分析。结果表明：随着生育期的延长，株高和花茎长均呈增高趋势，花序展开直径则持续下降，10月上旬花序直径为8．51cm，远小于7月中旬和8月下旬的花序直径（分别为9．81、9．59cm）。种球、根、叶和花茎全氮含量的动态变化较小；花茎全磷含量随生育期的延长而显著下降，从7月中旬的0．42％下降到10月上甸的0．23％，同样，花茎全钾含量也随生育期的延长而下降，7月中旬为3．99％...

Summary:以姜荷花‘清迈粉’品种为材料，于7月中旬、8月下旬和10月上旬分别取样测定了株高、花茎长、花序长及花序展开直径，同时对其根系、花茎、叶、原种球及新生仔球的全氮（N）、全磷（P）和全钾（K）等含量进行了测定，并进行了相关性分析。结果表明：随着生育期的延长，株高和花茎长均呈增高趋势，花序展开直径则持续下降，10月上旬花序直径为8．51cm，远小于7月中旬和8月下旬的花序直径（分别为9．81、9．59cm）。种球、根、叶和花茎全氮含量的动态变化较小；花茎全磷含量随生育期的延长而显著下降，从7月中旬的0．42％下降到10月上甸的0．23％，同样，花茎全钾含量也随生育期的延长而下降，7月中旬为3．99％，10月上旬仅为2．45％。新生仔球全氮（N）、全磷（P）和全钾（K）含量成熟期（12月上旬）均高于发育初期（10月上旬）。花茎长、花序长分别与N含量呈正相关。但均与P、K含量呈负相关：花序直径与P、K含量之间具有较高的正相关．其系数分别为0．901和0．842。

Plant height, scape length, inflorescence length and diameter of Curcuma alismatifolia ＇Chiangmai Pink＇ was measured 3times from July to October, and also the content of total N, P, K of root, leaves, scape and bulb were measured. The results show that： Plant height and scape length increased gradually from July to October. But, the inflorescence diameter decreased gradually. There was little change of N content for all organs. However, the contents of total P and K of scape were 0.23% and 2.45% measured in October, which were lower than that of July. The contents of total N, P, K of new bulb increased gradually from October to December. Scape length and inflorescence length were positively correlated with total N content of scape, but they were negatively correlated with P or K content. However, inflorescence diameter was positively correlated with total P or K content,and the correlation coefficient reached to 0.901and 0.842, respectively.
